SPIRIT1QTR

RF Transceiver ICS Overview

The SPIRIT1QTR is a very low-power RF transceiver intended for sub-1 GHz ISM band applications. It supports frequencies from 150 MHz to 956 MHz across multiple bands. The device features a maximum data rate of 500 kbps and an output power of 16 dBm. Key electrical parameters include a sensitivity of -118 dBm, supply voltage range of 1.8 V to 3.6 V, receive current of 9.2 mA to 9.8 mA, and transmit current of 6 mA to 54 mA. It operates within a temperature range of -40°C to 105°C.

RF Transceiver ICS Feature Summary

• Supports multiple modulation schemes including 2FSK, ASK, GFSK, GMSK, MSK, and OOK.
• Integrates hardware CRC checks and FEC encoding/decoding capabilities.
• Utilizes a serial interface (SPI) for communication with the host microcontroller.
• Designed for license-free operation in global sub-GHz ISM bands.

RF Transceiver ICS Applications

• Wireless M-BUS metering applications
• Low-cost short-range USB dongle transceivers
• ISM band wireless sensor networks
• Sub-GHz RF wireless remote control systems

RF Transceiver ICS Procurement Notes

Verify the specific package variant when ordering, as the QTR suffix indicates tape and reel packaging. Confirm that the application environment remains within the specified -40°C to 105°C operating temperature range. Ensure the host system provides the required 1.8 V to 3.6 V supply voltage. Check for any recent Product Change Notifications regarding manufacturing or labeling updates before finalizing procurement plans.

RF Transceiver ICS Selection Notes

Select this component for designs requiring ultra-low power consumption in sub-GHz applications. It is suitable for systems needing high sensitivity (-118 dBm) and moderate output power (16 dBm). The integrated baseband processing reduces MCU load by handling CRC and FEC. Consider the 20-VFQFN package constraints for PCB layout and thermal management during selection.

RF Transceiver ICS Part Context

This part belongs to the SPIRIT1 family of low-power transceivers from STMicroelectronics. It is commonly used in development kits such as STEVAL-IDS001V5 and STEVAL-IKR002V5, which pair the transceiver with STM32L microcontrollers. These kits demonstrate reference designs for PC GUI interaction and firmware updates via USB.

RF Transceiver ICS Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Designers should evaluate other sub-GHz transceivers based on pin compatibility and register-level software migration efforts if replacement is necessary.
